Description

V-method casting mold convenient to take mold and mold taking device Technical Field The invention belongs to the technical field of V-method casting, and particularly relates to a V-method casting mold convenient for mold taking and a mold taking device. Background The V-method casting is used as an advanced sand casting process, and is widely applied to a plurality of fields such as machine manufacturing, automobile part production and the like by virtue of the advantages of good sand mold collapsibility, high casting surface quality, small environmental pollution and the like. However, in the actual production process, the mold taking link always has a technical pain point to be solved urgently, and the improvement of the production efficiency and the casting quality is severely restricted. On one hand, for castings with complex structures (such as deep cavities, bosses, back-off, etc.), the corresponding positions on the mold often form structures that cannot be directly taken out of the mold. In the prior art, the method of designing the part as a detachable loose piece is generally adopted for adapting production, namely, after the molding of the mold is finished, the whole sand mold is firstly lifted from the mold main body, and then the loose pieces embedded into the sand mold are taken out one by one through manual operation. The method has the obvious defects that the process of taking out the movable block is additionally added, the production flow is prolonged, the production efficiency is greatly reduced, meanwhile, the movable block is tightly wrapped by the sand mold in the molding process, the sand mold has certain adhesive force, the labor intensity is high when the movable block is manually taken out, the sand mold is easily damaged and collapsed locally due to improper operation, the molding precision of the follow-up casting is further influenced, the casting is even scrapped, and the production cost is increased. On the other hand, in the casting process of the V method, in order to ensure that the molten metal smoothly fills the cavity and discharges the gas in the cavity, a sprue and a dead head are required to be arranged on the die. In the prior art, a sprue and a strain relief are manufactured in an integrated molding mode with a sand mold, and the sprue and the strain relief are taken out from a box-loading sand mold one by manpower after molding. The manual operation mode has the problems that firstly, the position distribution of a sprue and a strain relief is likely to be scattered, part of the position space is narrow, manual operation is inconvenient, the efficiency of taking a part is low, the requirement of large-scale batch production is difficult to adapt, secondly, the strength and the angle of manual taking of the part are difficult to accurately control, collision and scraping are easy to cause on a sand mold, the integrity of the sand mold is damaged, the quality of a casting is affected, and in addition, the actions such as bending and stretching repeatedly for a long time bring great labor intensity to operators, certain potential safety hazards exist, and the requirements of modern production on high efficiency, safety and labor saving are not met. Therefore, developing a V-method casting mold and a mold taking device capable of realizing efficient and nondestructive taking out of a movable block, a sprue and a strain relief is a technical problem to be solved in the current industry. Disclosure of Invention Aiming at the problems in the prior art, the invention provides the following technical scheme: a V-method casting mold convenient for mold removal, comprising: The base (10) is of a top cover-free design, and a fixing piece is arranged on the outer side face of the base (10) and used for fixing the base; The die comprises a die (11), wherein the die (11) is fixedly arranged at the center of the bottom of a base (10), an installation cavity is formed in the bottom of the die (11), a second telescopic cylinder (60) is installed on the inner wall of the installation cavity, a movable piece (20) is fixedly connected to the telescopic end of the second telescopic cylinder (60), and the movable piece (20) movably penetrates through the die (11) and protrudes out of the die (11) to form a movable block. As the optimization of the technical scheme, the die (11) is provided with a through hole, and the through hole is matched with the movable piece (20). As the optimization of the technical scheme, the movable piece (20) is sleeved on the periphery of the movable piece (20), and the outer diameter of the movable piece (20) is larger than the inner diameter of the through hole. The utility model provides a die picking device, die picking device is applied to the V method casting mould of foretell one kind of being convenient for die picking, die picking device includes: the support legs (30) are arranged on the periphery of the base (10); A translation mechanism compris
